Terry also used his programme notes for Sunday's Barclays Premier League game against QPR to say sorry to Blues supporters and pay tribute to the 10 men who produced a heroic comeback at the Nou Camp on Tuesday to reach next month's final.
The Chelsea captain wrote: "I want to start my notes today by saying how sorry I am for getting sent off at the Camp Nou and for putting the players, the manager and the club in that situation so early on in such an important game.
"I apologised to Robbie, the players and the staff after the game. I'm big enough to come out and man up when I make a mistake and, clearly, I made a mistake on Tuesday.
"I'm sorry for that and I owe it to you, the fans, to come out and say so.
"After that, for the boys to go and get the result they did, in the manner they did, was honestly one of the best things I have seen since I have been at Chelsea.
"It was not just the result, but the way they played.
"Just when it looked like everything was going wrong, for the 10 players on the pitch to stand up to one of the best teams ever to play the game, in their own stadium, was incredible.
"I was really proud to see the lads get through, because this football club and this group of players deserve the opportunity in the Champions League final."
